  • A robust hybrid tracking system for outdoor augmented reality

    Publication Year: 2004, Page(s):3 - 275
    Cited by:  Papers (41)  |  Patents (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (677 KB) | HTML iconHTML

    We present a real-time hybrid tracking system that integrates gyroscopes and line-based vision tracking technology. Gyroscope measurements are used to predict orientation and image line positions. Gyroscope drift is corrected by vision tracking. System robustness is achieved by using a heuristic control system to evaluate measurement quality and select measurements accordingly. Experiments show th... View full abstract»

    This paper describes the implementation of hybrid tracking software that is capable of operating both indoors and outdoors. Commercially available outdoor trackers are combined with an indoor tracker based on fiducial markers and video cameras. The position and orientation of the user's body is measured in physical world coordinates at all times, and tracking of the hands is performed relative to ... View full abstract»

  • Tracker calibration using tetrahedral mesh and tricubic spline models of warp

    Publication Year: 2004, Page(s):19 - 26
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (987 KB) | HTML iconHTML

    This paper presents a three-level tracker calibration system that greatly reduces errors in tracked position and orientation. The first level computes an error-minimizing rigid body transform that eliminates the need for precise alignment of a tracker base frame. The second corrects for field warp by interpolating correction values stored with vertices in a tetrahedrization of warped space. The th... View full abstract»

  • Increasing the effective egocentric field of view with proprioceptive and tactile feedback

    Multimodality often exhibits synergistic effects: each modality compliments and compensates for other modalities in transferring coherent, unambiguous, and enriched information for higher interaction efficiency and improved sense of presence. In this paper, we explore one such phenomenon: a positive interaction among the geometric field of view, proprioceptive interaction, and tactile feedback. We... View full abstract»

    This paper describes the underlying concepts and the technical implementation of a system for resolving multi-modal references in virtual reality (VR). In this system the temporal and semantic relations intrinsic to referential utterances are expressed as a constraint satisfaction problem, where the propositional value of each referential unit during a multimodal dialogue updates incrementally the...

  • Projection based olfactory display with nose tracking

    Most attempts to realize an olfactory display have involved capturing and synthesizing the odor, processes that still pose many challenging problems. These difficulties are mainly due to the mechanism of human olfaction, in which a set of so-called "primary odors" has not been found. Instead, we focus on spatio-temporal control of odor rather than synthesizing odor itself. Many existing interactiv... View full abstract»

  • Food simulator: a haptic interface for biting

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (682 KB) | HTML iconHTML

    The food simulator is a haptic interface that presents biting force. The taste of food arises from a combination of chemical, auditory, olfactory and haptic sensation. Haptic sensation while eating has been an ongoing problem in taste display. The food simulator generates a force on the user's teeth as an indication of food texture. The device is composed of four linkages. The mechanical configura... View full abstract»

    This paper describes in detail the design, development, and evaluation of the TWISTER III (Telexistence Wide-angle Immersive STEReoscope) and demonstrates how this system can display immersive three-dimensional full-color and live motion pictures without the need for special eye-wear. The device works as a cylindrical display by rotating 30 display units around an observer and presenting time-vary... View full abstract»

  • Omnistereo for panoramic virtual environment display systems

    This paper discusses the use of omnidirectional stereo for panoramic virtual environments. It presents two methods for real-time rendering of omnistereo images. Conventional perspective stereo is correct everywhere in the visual field, but only in one view direction. Omnistereo is correct in every view direction, but only in the center of the visual field, degrading in the periphery. Omnistereo im... View full abstract»

    We present a collaborative desktop virtual and augmented reality system with a shared physical workspace: the joint space station. It is constructed out of multiple, single-user near-field virtual or augmented reality stations using mirror-based displays. The joint space station provides high-resolution stereoscopic images and direct 3D interaction to all participants. The environment is modular, ... View full abstract»

    Collision detection for dynamic objects in distributed virtual environments is still an open research topic. The problems of network latency and available network bandwidth prevent exact common solutions. The consistency-throughput tradeoff states that a distributed virtual environment cannot be consistent and highly dynamic at the same time. Remote object visualization is used to extrapolate and ...
